Research on network security situation awareness method based on topology analysis

due to the long response time of network security situation awareness method, a network security situation awareness method based on topology analysis is proposed. Through the analysis of time dimension host layer security situation and space-time dimension network layer security situation, the network security threat index is determined, and the network security situation awareness method is determined based on the topology analysis. The experimental results show that this method can effectively improve the situation of network security situational awareness, and has certain practicability.
